Theoretical investigation of the role of bending waves in the conditions for observing optical bistability in layered semiconductors is performed using the Green function method. By the example of 2H-polytype of PbI2, we show that efficient exciton scattering by the oscillations of this type leads to a short-wave shift of the frequency region of optical bistability, decrease in the size of this region, widening of temperature interval of its observation, a shift of the hysteresis loop towards higher intensities and a decrease in its height and width.

Key words: optical bistability, layered crystal, bending wave, exciton-phonon interaction
